Using SNMP Version 1, the network manager can issue three types of com-
mands:
•
GetRequest
: This command retrieves a single item or the first in a series
from a network device.
•
GetNextRequest
: This command retrieves the next item in a series from
a network device.
•
SetRequest
: This command writes information to a network device.
The network device issues two types of messages:
•
GetResponse
: This message is the response to a network manager GetRe-
quest
or GetNextRequest command.
•
Trap
: This is an unsolicited message issued by a network device to report
an operational anomaly or an alarm condition to the network manager.
These messages are typically encased within informational packets and trans-
ported over the LAN or WAN.
